the bottom half of michigan is huge. i grow in the top half and have no problem with finding spots every year. look at Yankee Springs, John Ball Park in GR. Huron Manistee forest is so massive they would never see anything.
human hair will take care of deer or piss in a gallon jug for a few days and then pour it around your area, or this is sick but it works...a used tampon works due to the blood...hang that fucker in a tree near your spot and animals wil run and if anyone runs across it hiking or something they will think its a sick joke and take off the other way.
